' This invention relates to a sham motor cycle "for amusement purposes,'the main teature'of which consists in th s, that a com.-

pressed "air system is provided in, the cycle,

One of the cylinders of the sham motor is utilized as a reservoir for the compressed air system, formed by a rubber ball- Within the said cylinder. 7 r

In addition to the combination with a compressed air system provided in the cycle, which by means of separate valves operates whistles, blowing devices and the like, of other means having a comic eiiect may be provided, such as a petrol tank having a series of holes for the reception of fire-v works, for instance crackers and the "like, and spark producing the fireworks or a revolver below the exhaust pipe operated by means of a pull member.

In the accompanying drawing 'a constructional example of the invention is illustrated, the fig'ure' showing L IIlOlZOI cycle partly in side elevation andpartlyi'n seetio'n. I

1 and 2 are the two wheels. is the frame of the motor cycle, 4 the engine and 5'the handle bar and 6 the saddle. Under the saddle and fixed to the same and'the supporting plate 7 is a pumping device 8, which for instance has the form of a pair of bellows. The intake valve of the pump ing'device is in the supporting plate 7 The compressed air is withdrawn from the forward end of the pumping device and'is conveyed through a flexible tube 9, which preferably passes through a tube of the frame to the rear cylinder 10 of the engine l. In this cylinder is a rubber ball 11,

which is constructed in a known manner to form an air reservoir 11. The airreservoir 11 is provided with an inlet valve at the point of entrance of the flexible tube 9. The compressed air is distributed froin the air reservoir "11 to the Various points,"

where it is to be used; By means of the valve 12 compressed air is conveyed either devices for exploding connected a cord 32 extending along the lower side oit'the exhaust pipe 15. The cord a through 1 T- shaped tube the I two trill whistles 14, which are made to imitate fir-sa as henna ii'oLA'As, or BERLIN, GERMANY, Ass eivoR-ro oHANNA KLEIN, or shoes,

by the current of air thus produced and forms a'cloud likeismoke behind the travel "ling cycle The valve ;is.operated by means of the cord 17i'and-the hand-lever 18 The imitation petrol'tank ,"1-9, which is mounted on the horizontalupper tube ot'the frame is provided with a series of holes 20. In the petrol'tank fireworks such as crackers or,

the-like are caused to explode by any known spark producing device. The exploding fireworks fly through the holes 20 and create the impression that the petrol tank is ex ploding. On the forward supporting tube 21 of the frame 3 ofthe cycle is a signalling device. This device consists of a diaphragm 22 mounted in a tunnel, which diaphragm s-caused to vibrateby means-of a shaft 23 and a small wheel 2a resting on the tyrev of the front wheel 1 ofthe cycle. By suitably tuning the signalling device, very comic signals can be produced. WVithtne objector imitating the noise of an engine a vertical diaphragm 26'isstretched in the forward cylinder 25. On a. small .drum Q? is a pin 28, which, on the drum 27-150- tat ng, strikes against thediaphragmflti.

Through the rapid succession of blowsgiven by the pin 28 against the diaphragm 26 a noise is produced similar tothat 01": an engine. The drum 27 is driven by a small belt 29 from the pulley30.

tor, cycle, which belt is driven from the rear wheel 2 of the motor cycle. Thecranks a This pulley ;1s itself driven by the belt 3 t'o'f'the'mol are marked Below the rear outlet of the exhaust pipe 15 afsmall pistol 33 is To the trigger or the pistol 33' is passes in front of the engine t along the frame of the handle bar 5, where it is con- -nected to an operating lever 35. By press ing the lever 35 the trigger of the pistol 33 the engine. 36 and 37 are the twofmuds guards of the wheels land 2.

The sham motor cycle described above is intended as a trick'device for comic artistes. The cycle is intended to create the appearance of a motor cycle and to reproduce B 3101565 characteristic of a motor .cycle, "per-i haps in a somewhat exaggerate'dgmanner.
